It's ironic that such things are made possible by the degree to which computers are being locked down --- a "factory reset" isn't really, if all it does is reinstall from a "recovery" on the device itself.
xhelper certainly won't survive a full reimage, which is an actual "factory reset" and only available to those with fully unlocked phones such as some of the Mediatek-based ones. That's done by holding down a button while plugging into USB with the battery disconnected, which causes it to go into BootROM mode (and this is really a ROM). Then SPFlashTool can be used to erase and rewrite the entire internal eMMC.
